SNAP HOOK.

SPEGIFIGATIUN forming' oart of Letters Patent No, 744,860, dated November 24, 1903. Application filed March 18,1902. Renewed May 14, 1903. Serial No. 157,189. (No model.)

. T a/ZZ whom it may concern:

Be it known that I, JONATHAN F. ELLs- WORTH, a citizen of the United States, residing at Hyannis, in the county of Grant and State of Nebraska, have invented certain new and useful Improvements in Snap-Hooks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to snap-hooks and is designed as an improvement on Letters Patent No. 676,981, granted June 25, 1901.

In the patent above referred to I have discovered that the loops to which the cross-bar is connected greatly weakens the side pieces, and to overcome this objection I have provided the side bars with reinforcing-sleeves, which bridge the opening between the sides of the loops, and thus materially strengthens the side pieces.

The invention consists of a snap-hook comprising a split ring and a halter-receiving part connected by side wires, said ring opening upon compression of the hook, and a device situated intermediate the side wires to cause the lateral separation of the parts of the opened ring by compression of the hook, said device comprising a transverse loop in each wire, connected to its fellow by a bar, and sleeves for closing or bridging the space formed between the sides of the loops, and thus materially strengthening the side pieces and relieving them of strain at those points at which the loops are formed.

In the accompanying drawings, Figure l is a perspective view of my improved snap-hook. Fig. 2 is a transverse section looking toward the split ring, showing in full lines the members of the split ring closed and in dotted lines showing them open. Fig. 3 is a transverse sectional view through one of the loops looking down upon the sleeve; and Fig. 4 is a view of one of the side pieces of the snaphook, illustrating the loop before the sleeve has been applie Referring to the drawings, 1 denotes a socalled snap-hook formed of a single piece of wire bent to produceastrap-receiving part to cause the side wires 7 to move in planes uniformly situated with respect to each other in order to move the wire ends 5 obliquely apart, as indicated in Fig. 2 in full and broken lines.

In practice it has been found that the side wires or pieces 7 are materially weakened by forming the loops or bends 8 therein, and to overcome this objection I provide a split sleeve 10, which bridges the space formed by the side pieces 11 of the loops and surrounds thepieces 7 immediately contiguous to the side pieces of said loops and extends some little distance along the side pieces 7 in the opposite direction from said loops. The present invention lies in this feature and materially increases the life of the snap-hook.

Having thus described my invention, what I claim, and desire to secure by. Letters Patent, is-

A snap-hook comprising a split ring, and a halter-receiving part connected byside wires, said ring opening upon compression of the hook, and a device situated intermediate the side wires to cause the lateral separation of the parts of the opened ring by compression of the hook, said device comprising a transverse loop in each wire connected to its fellow bya bar, and sleeves for closing or bridging the space formed between the sides of the loops, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
